Javascript/Coffeescript 在值相同时对多个键上的对象数组进行排序

Posted 2023-03-03

【中文标题】Javascript/Coffeescript 在值相同时对多个键上的对象数组进行排序

【英文标题】：Javascript/Coffeescript Sorting an array of objects on multiple keys when the values are the same

【问题描述】：

我正在尝试按键对对象数组进行排序，但是当对象 a 的键值与对象 b 的键值相同时，将检查下一个键，直到它们最终不同为止。

我尝试过使用以下代码：

rows.sort (a, b) ->
   for key, value of a
      if a[key] < b[key]
        return -1
      else if a[key] > b[key]
        return 1
      else
        continue

但是当初始顺序不同时，这会导致数组看起来不同。关于实现它的方法的任何想法？ 谢谢！

【问题讨论】：

感谢您的评论，添加以澄清。我希望排序数组的第一个示例每次都会推出。

实际上，只要总是返回相同的订单，哪一个并不重要。

【参考方案1】：

您不需要continue。并确保在对象匹配时返回0：

rows.sort (a, b) ->
  for key, value of a
    if a[key] < b[key]
      return -1
    else if a[key] > b[key]
      return 1

  return 0

更大的问题 - 对象键未排序。没有理由期望，每次通过 for 循环时，第一个键将是日期，第二个键将是 cpc，等等。您确实希望按顺序拥有一个预定义的键数组，并使用它而不是仅仅从对象中获取密钥列表

keys = ["a","b","c"]

rows.sort (a, b) ->
  for key in keys
    if a[key] < b[key]
      return -1
    else if a[key] > b[key]
     return 1

  return 0

Example

【讨论】：

哇哦。首先，感谢您的快速回复！我是如此专注于下一个键，我什至没有想到这一点。如此明显。太感谢了！尽管如此，当初始数组的顺序不同时，我仍然会得到不同的顺序。

那么您需要发布一个显示问题的数组示例（在问题中，而不是作为评论，以获得最佳结果）。

是的，抱歉，已添加！ ;)（之前没有添加，因为它们很长）

更大的问题 - 对象键没有排序。没有理由期望，每次通过for 循环，第一个key 将是date，第二个将是cpc，等等。你真的想要一个预定义的键数组，在顺序，并使用它而不是仅仅从对象中获取 key 列表。

@muistooshort 好点。用代码将其移至答案。

【参考方案2】：

我本来想问这个问题，但发现有一个类似的问题，结果发现答案是我已经在做的事情，但这有一个 FOR IN 循环。 我测试了它并没有给我想要的东西 然后，当值相同时，我决定将 for in 循环换成更多代码。 这是结果
